Scope

Main technical content: This standard is based on the national PVB industry standard JC/2166-2013, and some improvements and enhancements have been made based on industry market demands and practical situations. a. For product classification and codes, the national industry standard is largely retained, with minor modifications and additions. Additionally, due to customers' marketing needs for the product, it has been separated from the classification. b. For product internal quality requirements, improvements have been made in terms of appearance, physical and mechanical properties. 1. For appearance defects, modifications have been made to the number and length of joints. 2. For internal quality, two indicators, such as moisture pass rate and heat shrinkage rate, have been modified to be more stringent. 3. Some marketing-unfriendly indicators, such as the yellow index, have been removed, and three new quality indicators, including peel strength, impact resistance, and penetration resistance, have been added. c. For the determination of quality inspection results, clearer regulations have been made based on actual situations. The formulation of the above standard is more specific and practical than the 2013 industry standard, and it is easier to grasp and implement in the production process and market trading process.
